The audience applauded each time any of the three musicians took solos, nice. People could not contain their admiration for what just happened but makes for a few other questions like how much more important is the solo than the whole piece? If there isn’t applause for the next soloist does that convey inadequacy of their playing? And doesn’t the audience now feel pressure to applaud every solo no matter whether they were moved? Sort of like the dilemma when an audience starts to clap along to music and then the musicians who they were ostensibly supporting, have to make musical choices different than what they planned to present because the claps flam or slow down etc.

In the classical world a movement ends and even if you were blown away you remain quiet, nothing like it. You might be bursting with admiration but stay still, enjoy the silences let the piece complete itself. Some old ways are pretty modern.
